Eva air allows you to cancel your ticket without penalty if you cancel within 24 hours of booking and submit a refund application within 24 hours of purchase.
If you meet all of these conditions, you will receive a full refund for your ticket, minus any applicable taxes and fees. The Eva air 24-hour cancellation policy does not apply to all types of tickets, and if you cancel your ticket after 24 hours of booking, you will be subject to a cancellation fee.
